^ Israel has annexed and administers the Golan Heights territory, which includes part of Mount Hermon, but its territorial claim is not recognized in international law and the area is considered by the international community to be a part of Syria and not Israel.

^Monalanong Hill is a mountain often considered the highest point of Botswana, with a questioned altitude of 1,494 metres (4,900 feet). This datum comes from the SRTM database just as the 1,491 m for Otse. The error range of these data is significantly higher (approximately 15 m), but a British explorer did a GPS reading on the top of both hills, and his measurement showed Otse slightly higher.
